Shape Maps
The plugin currently supports US maps and state names. The model and data styles for the subsequent examples are:
explore: airports is table('malloy-data.faa.airports') { primary_key: code measure: airport_count is count() query: by_state is { where: state != null group_by: state aggregate: airport_count } }
Data Styles
{ "by_state": { "renderer": "shape_map" } }
Run as a simple query
query: airports -> { nest: by_state }| by_​state |

Run as a trellis
By calling the configured map as a nested subtable, a trellis is formed.
